This is in part not a bad idea.
If they were fed properly - Bettas would probably be much happier in a
bowl filled with roots as opposed to a bare bowl. In the wild Bettas are
at home in densely vegetated waters and should appreciate the cover.
Also the roots will absorb fish waste which is mutually beneficial to
the fish and the plant. Ray Wolff & I and many others have often let
cuttings of Philodendrons and Pothos grow in our tanks and tubs.
But we do still feed the fish and change the water!
